8. Asking in detail about her past sexual relationships

Thinstock

Couples talk about their pasts, especially the where past relationships and sex are involved. Talking about the sexual past is a way to find out the likes and dislikes of your partner and it’s also usually a good indicator of which sexual acts are up for discussion and which are completely off limits. It's only natural that you'd ask about her sexual resume. Just don't seem too interested. You don't need to know every graphic detail and all the who, what, where, and how many times. It makes it seem like you’re less interested in her as a serious sexual partner and more as a sexual fantasy.
